Full Description

The Eleusinian Mysteries (~1500 BCE - 396 AD) operated continuously for approximately 2,000 years — the longest documented use of consciousness-altering ritual technology in history. Participants experienced "metanoia" — profound transformation of consciousness functionally equivalent to an NDE. The experience used darkness, fasting, sensory deprivation, and unknown substances (kykeon). Details were kept so secret that revealing them was punishable by death. This suggests the experience was so powerful that maintaining its secrecy was considered essential to its function and to social stability.
